I do not own Harry Potter. JKR does.
Like a powerful guiding force, Harry felt Draco's tired, thin lips on his and at once he understood, albeit reluctantly, the chaste kiss the Death Eater was giving him. Draco was begging for forgiveness after the years of bullying Hermione Granger, shaming Ron and his family, lording his wealth and status above others and almost executing Dumbledore. For a boy who was raised in taking what was rightfully yours, the fact he didn't part his mouth just once to invade Potter's was a surprise.
Harry broke the kiss, his green eyes narrowed with embarrassment, humiliation and maybe a flicker of wanting. The sensation vanished as soon as it was felt.
"This changes nothing, Malfoy," he spoke indignantly, wiping the kiss off his lips with the back of his hand, still tasting the snake. A chord had been struck somewhere deep inside Harry, a note waiting to be played again.
A weak smirk crossed Draco's face. In the hours after the battle, he had aged so much. His past decisions weighed down on his personal appearance, dark circles under those cloudy steel-grey eyes of his. "I believe it does Potter. It makes up for the handshake you refused me so long ago."
So I'm not much of a slashfic writer, but this was a nice exercise to write a pairing that wasn't my usual fare. I apologize for the OOC-ness and all around shittiness.
